When Pro Tools version 10 (10.3.6+) and 11 are installed on the same Mac, any EDI application functions that control Pro Tools via keystrokes will only interface with the Pro Tools 11 installation.

Examples of functions that send keystrokes to Pro Tools:

EdiLoad - Pro Tools re-conform

EdiCue - Send to Clip, Get from Clip

EdiPrompt - Cue List rename and locate

If you need to use the Pro Tools 10 instead then they recommend the simplest work-around is to zip and then delete the Pro Tools 11 application file found in the Applications folder so the the Mac OS can only see Pro Tools 10.3.6 as it will direct any key commands to the Pro Tools 10 installation. To restore Pro Tools 11 simply unzip the archive that was created.
